Title: Improvements in connection with the braking of motor and like vehicles
IPC: B60T13/16
Filed: 1925-01-17
Abstract: 248,144. Murray, T. B., and Albion Motor Car Co., Ltd. Jan. 17, 1925. Fluid-pressure.-Relates to brakes for motor and like vehicles in which the manual application is augmented by the propelling mechanism of the vehicle through a pump, which pumps liquid unidirectionally irrespective of the direction of movement of the vehicle and generates hydraulic pressure in a cylinder operatively connected to the brake. The train for operating the brake includes a floating lever connected to the means for determining the fluid pressure generated in the cylinder. The floating lever 6 is connected at one end to the brake pedal 9, intermediately to the brake rodding 5, and at the other end to the valve 12 controlling the byepass 13 through which oil is normally circulated by the pump 18. On manual application of the brake through the rodding 5, the valve 12 is moved to close the bye-pass 13 and oil is forced into the cylinder 2 and exerts pressure on a piston 4 mounted on a rod connected to the rodding 5. The gear wheels of the pump 18 are driven from the rear wheels of the vehicle. The pump comprises inlet passages 25 and outlet passages 27 branching to each side of the pump and controlled by non-return ball valves 23, 24. Independent cylinders may be provided for each brake, including the front-wheel brakes or trailer brakes. According to the Provisional Specification, the brake pedal may control the byepass valve only, and a hydraulic accumulator may be included in the byepass pipe line.

Title: Improvements in electrical oscillation generators
IPC: H03K3/78
Filed: 1941-02-04
Abstract: 584,726. Valve generating circuits ; super-regenerative circuits ; relaxation oscillators. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., RUST, N. M., PARTINGTON, G. E., PLAISTOWE, D. L., and FEWINGS, D. J. Feb. 4, 1941, No. 1480. [Class 40 (v)] A valve is arranged to operate both as a radio-frequency oscillator and as a blocking pulse generator, so that pulses of radio-frequency energy are produced. The circuit is employed for transmission and/or for superregenerative reception. As shown in Fig. 1, the radio-frequency circuit comprises a Lecher pair TL connected to the grid and anode of a valve T, and the pulse is produced by a transformer TR coupling the grid and plate circuits, its frequency being determined by a resistance and capacity in the cathode leg. Chokes CH2, CH3 keep the radio frequency from the transformer TR. In Fig. 4 an auto-transformer AT is used for the pulse generator, and signal voltage is applied at a transformer TR1, in the anode circuit. The signal voltage may produce amplitude or frequency modulation of the pulses, and the same circuit may be used for reception of signals sent by a similar transmitter, anode voltage is reduced, the receiving instrument being associated with the transformer TR1. The circuit may also be used as a super-regenerative receiver of waves sent from a normal transmitter. Normal tuned circuits may be used instead of the Lecher pairs, and two valves may be connected to such tuned circuit in push-pull relation, (Fig. 5 not shown). The line pair TL may have a condenser across its outer end of capacity equal to that between anode and grid, the pulse transformer then being connected to the mid-points of the line.

Title: Method and devices for the manufacture of gases containing acetylene
IPC: C07C4/02
Filed: 1962-01-16
Abstract: Gases containing acetylene are obtained by contacting hydrocarbons with a bath of molten material at 1100 DEG -1800 DEG C. and cooling the gases obtained.  The hydrocarbon is preferably a gas, e.g. natural gas or may be a liquid or vapour, and is preferably preheated.  It is contacted with the molten liquid by passing it through holes in the bottom of the bath or blowing it downwardly through a pipe above the bath at an angle to the horizontal so that the hydrocarbon penetrates the liquid.  Suitable materials for the bath are metals, alloys and slags, e.g. molten copper, bronze or cast iron and is preferably electrically heated by inductance, resistance or arc.  The gases are cooled by direct or indirect contact with a cooling fluid, e.g. water.

The channels 9, 10 may be formed in the face of the kerb as shown or they may be formed as holes leading from the recess to the upper and front faces of the kerb respectively. The casing may have an integrally formed or an attached upstanding lug or channel member which may constitute a part of the boundary of the channel 9 and which assists also in positioning the casing in the mould when the kerb is made by casting. Reflectors and channels may be provided at both ends of the recess.

Title: Improvements in or relating to electrical devices and circuits for producing alternating currents with a desired phase
IPC: G01S1/02
Filed: 1940-01-29
Abstract: 568,785. Converting electric currents. BROWNE. C. O. Jan. 29. 1940, No. 1757. [Class 38 (ii)] [Also in Group XL] An adjustable electrostatic coupling device, applicable as a goniometer or as a phase transformer, comprises a pair of rotor electrodes whose active surfaces lie in a surface of revolution and are separated by a gap which does not lie in a plane perpendicular to the axis and a set of stator electrodes lying adjacent to the active surfaces of the rotor electrodes. The gap is shaped so that the coupling variation with angular movement of the rotor follows a sinusoidal or other desired law. The system is shown in Fig. 2, in which opposed pairs of stator plates 5 are supplied from sources A, B and the rotor electrodes 4<SP>1</SP>, 4<SP>11</SP> are connected to a load L, all the electrodes forming parts of concentric cylinders. The narrow gap between the rotor plates 4<SP>1</SP>, 4<SP>11</SP> lies in a plane inclined to the axis of the cylinders, so that when the cylinders are developed into plane surfaces, as shown in Fig. 1, the gap follows a sinusoidal curve 9. The plates 4<SP>1</SP>, 4<SP>11</SP> are wider than the stator plates 5 in the axial direction, and their outer margins form capacity couplings with fixed plates 7 by which current may be taken to the load L without the use of rubbing surfaces. When used as a goniometer, the inputs A, B comprise two directional aerials, while for phase transforma.- tion, the inputs A, B are in phase quadrature. To maintain a. constant load on the input sources for all settings of the rotor, a second similar device may have its rotor connected to a dummy load and set at right angles to the first rotor. Modifications employing three stator plates or eight stator plates are referred to. The elements described above as rotors may bo fixed, and those described as stators adjustable.

Title: Improvements relating to track braking apparatus

Abstract: 694,212. Railway track braking apparatus. METROPOLITAN - VICKERS - G.R.S., Ltd. Dec. 20, 1951 [Jan. 30, 1951]. No. 2327/51. Class 103 (i). In track braking apparatus for railway vehicles of the type in which braking rails arranged alongside the running rails are moved into engagement with the wheels of vehicles, the operating mechanism is such that the planes of the braking surfaces of the rails remain substantially parallel throughout the range of their movement. This is accomplished by the use of a mechanism, as shown diagrammatically in Fig. 1, comprising L-shaped members 1 and 2, to the arms of which is pivoted a bell-crank member 5 so that a force F applied as shown causes a parallel movement of the rails 3 and 4, the reaction between the members 1 and 2 being resisted by a roller 8. In a practical application, as shown in Figs. 3 and 4, the braking rail 13 on the inner side of the wheel is secured at the ends of the vertical limbs of two parallel L-shaped plates 16, 17, a pneumatic or hydraulic actuator cylinder 20 being secured between their opposite ends. The plates are connected by pins 21, 22 having rollers 23, 24 which run on tracks secured to the tops of the sleepers. The outer braking rail 12 is carried by a pair of parallel plates 18 and 19 which have a horizontal limb extending between the plates 16 and 17 and engaging the underside of a reaction roller (not shown) mounted centrally on the pin 22. The plates 18 and 19 are also connected by a pin 30, the position of which in a slot may be adjusted by nuts 31 on a drawbolt 29. The brake is applied by actuation of cylinder 20 which by moving upwardly the outer ends of two parallel plates 33 causes the pairs of plates 16. 17 and 18, 19 to be moved to engage the braking rails on the wheels.
